Frequently generated combinations of alerts were analyzed for associations in a 5% random data sample (dataset 1). Alert combinations with similar management recommendations were defined as clusters. The alert rate was assessed by simulating a CDSS generating 1 alert per cluster per patient instead of separate alerts. The simulation was performed in dataset 1 and replicated in another 5% data sample (dataset 2).<\/jats:p>\n               <jats:p>Results: Data were extracted from the CDSSs of 123 community pharmacies. Dataset 1 consisted of 841\u2009572 dispensed prescriptions and 298\u2009261 drug interaction alerts. Dataset 2 was comparable. Twenty-two frequently occurring alert combinations were identified. Analysis of these associated alert combinations for similar management recommendations resulted in 3 clusters (related to renal function, electrolytes, diabetes, and cardiovascular diseases). Using the clusters in alert generation reduced the alert rate within these clusters by 53\u201370%. The overall number of drug interaction alerts was reduced by 11% in dataset 1 and by 12% in dataset 2. This corresponds to a decrease of 21 alerts per pharmacy per day.<\/jats:p>\n               <jats:p>Discussion and conclusion: Using clusters of drug interaction alerts with similar management recommendations in CDSSs can substantially decrease the overall alert rate. Further research is needed to establish the applicability of this concept in daily practice.<\/jats:p>","DOI":"10.1093\/jamia\/ocw049","type":"journal-article","created":{"date-parts":[[2016,4,24]],"date-time":"2016-04-24T00:18:19Z","timestamp":1461457099000},"page":"54-59","source":"Crossref","is-referenced-by-count":16,"title":["Lower
